Often enough, the underlying       algorithms haven't changed.              Sometimes it is done with a wrapper, that then calls       the old routine. Or one can rewrite the first lines,       to give the right values to variables, and then into       the original code.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
